Stored Product Pests are tough to find without proper monitoring tools. Pheromone monitoring traps assist in narrowing down and focusing the inspection to specific areas. Monitoring pest populations and controlling these populations are quite different concepts. When we monitor, we are in an information-gathering stage. Professionals are trying to discover who is in the facility, in what quantity and in what area. We then take that information and focus our inspection to find the source of the population and determine a control technique. Successful control is hard and often impossible without monitoring. Δ-shaped traps can be placed in different areas and give the professionals all the information needed. Those are combined with specific pheromone lures which are addressed to the common stored product pests that professionals suspect that can be found in the premises or warehouse.
